The chemical contamination of water from a wide range of toxic derivatives, in particular organic molecules, is a serious environmental problem owing to their potential human toxicity. Among all the treatments proposed, adsorption is one of the most current methods for the removal of pollutants from the water. In this paper, we addressed the issue of using calcined double layered hydroxides (ZnAl-CO3DLH) at molar ration r=4 as adsorbent for Diclofenac sodium (DS) under the batch reactor operations in order to remove DS from aqueous solution. This work focused on the equilibrium isotherms and kinetics of the adsorption. The adsorption data fitted well to Langmuir isotherm. The maximum adsorption capacity of diclofenac was estimated to be 451.66 mg/g. In conclusion, the expanding of calcined ZnAl-CO3LDH adsorption represents a plausible and powerful circumstance, leading to a great improvement of environmental protection.
